| Abstract(in English) | Usually a single-pinhole camera is used for X-ray imaging. The limitation of the single-pinhole camera is that it can not combine good collection efficiency with high resolution. In URA camera, the pinhole is replaced by multi-pinholes arrays arranged in m-sequences. So the URA camera can provide an image with a high resolution and high SN ratio, and image distant planar sources with no artifacts. Furthermore, since the URA camera can view the object with a large solid angle, it can also provide some tomographic resolution for a three-dimensional object. In this paper, we present a quantitative evaluation of the tomographic resolution and propose a new method to improve the tomographic resolution. |
